 This is a topwork at about eye level that I did a few years ago. I read an interesting comment on a fruit group from a knowledgeable guy in Alberta. he felt that if you are grafting to crab apple roots, high versus low grafts can some what change when the tree wakes up in the spring. I wonder if it also changes when the tree goes dormant in the fall. I think he was referring to apple scion going on crab apple roots. They mostly use ranetka type roots up there from what I have read. Or Siberian, if there is a difference. Does anyone else note crabs waking up earlier? Does it vary with naturalized(wild) crabs versus purchased crabs? Differences in going dormant in the fall? |

I'll have to pay more attention. This year probably isn't a great one for determining wake up times

Some of my crab apples are waking up. I can’t see a reason why one here and one there.

Some of my crab apples are waking up. I can’t see a reason why one here and one there. I've got a Trailman at half inch green. That one is grafted to a wild crab rootstock. My Trailman on a Frankentree (your Swamp crab is the interstem, common domestic apple roots) is at green tip. They are about 100 yards apart |

I have some apple trees with 1/2 inch leaves while others are completely dormant nearby. I’ve given up trying to figure it out.
I’m happy to see my pear trees appear to have life this spring. The drought last year caused a total fruit failure on them and they dropped leaves very early. I was worried they would croak, but they look like normal right now.

My Trailman on a Frankentree (your Swamp crab is the interstem, common domestic apple roots) is at green tip. They are about 100 yards apart One Swamp crab is at that point and a chestnut crab. Two more chestnut crabs are not and then another one is. I was messaging Luke at Midwest Deer Trees and he and I think it varies with variety of the crab and rootstock as well as microclimate. I feel microclimate can vary by a few yards on my place due to changes in soil and frost depth due to our last winter. |

I don't think we'll ever know "answers" definitively, simply because there are too many unknown (unknowable?) variables.
